As the topic reveal, it's the airbase of the Danish Navy close to Copenhagen, however during the German occupation.
At Aalborg in Northern Denmark was a likely amphibious airbase built by the Germans, however here the aircraft was moored along a pier and the only access to ground was a large swinging crane wich lifted the aircraft from the water and onto trolleys on wich they could be tugged around. Hence it's surprising how many aircraft is to spot on dry land in this picture.
The BV 138 itself is a remarkable aircraft: The engines is two-stroke diesels and the lack of valves in the two-stroke engine is used to let 12 pistons operate against(!) each other in 6 cylinders by the use of two crankshaft - An opposite boxer-engine so to say.
The gain was the 'mileage' of the diesel, hence the 138 had a range of 4300km's :-o
The BV 138 dissapeared out of history and the only one to be exposed is one used as target during a post war RAF airshow, hence getting sunk in the waters east of Copenhagen and only to be found during excavation for the bridge spanning Öresund between Denmark and Sweden. It is however terrible corroded hence presented As a 'found at the seabed' -diorame at the Danish national tech museum in Helsingör (@Hamlets Elsinore). There is however several JUMO 205D engines to se around the world. Copenhageners have reported the remarkable seaplane to be extreme high pitched noisy, possible due to the neccesary ridgid sprocket connection of the two distant cranckshaft.
The engine did by the way find way into postwar Soviet and British tanks (If You Youtube the Chieftain tank You will experience the remarkable sound of the opposed six-cylinder twostroke!) and in an incredible triangonal configuration as the reknown Deltic engine for British postwar torpedoboats and later in diesel locomotives. Due to the calculation have the Deltic 3 cranckshaft; 18 cylinders and 36 pistons!
